The correct answer is B. cilia.

Cilia are small hair-like projections that extend from the surface of certain types of epithelial cells. They are involved in a variety of functions such as movement of mucus in the respiratory tract, movement of egg cells in the female reproductive system, and movement of sperm cells in the male reproductive system.
